C ++代码是: std::string value( (const char *)valueBegin, (const char *)valueEnd ); 这是使用string :: string构造函数: template<class InputIterator> string (InputIterator begin, InputIterator end); 任何人都可以帮助我将其转换为C代码吗? 谢谢!

某些情况下会带来意外的开销。比如非 const 成员使用[],这会触发 COW,因为无法知晓应用程序是否会对返回的字符做修改。典型的如Legality of COW std::string implementation in C++11中举的例子: std::strings("str");constchar* p = s.data();
Another way is to store characters fromstringintovectorcontainer and then use its powerful built-in methods to manipulate data safely. #include<iostream>#include<iterator>#include<string>#include<vector>using std::cin;using std::cout;using std::endl;using std::string;using std::vector;intmain(...
